What two numbers multiply to 690 and add up to 61?

Here we answer the question: "What two numbers multiply to 690 and add up to 61?"

The answer to your question is:

15 and 46

Below we illustrate and prove that 15 and 46 multiply to 690 and add up to 61:

15 × 46 = 690
15 + 46 = 61

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 61x + 690 = 0

If so, the solution to factor the quadratic equation above is:

(x + 15 ) (x + 46)

To summarize, since 15 and 46 multiply to 690 and add up 61, you know that the following is true:

x² + 61x + 690 = (x + 15 ) (x + 46)
